' I This invention relates to adding machines or to computing machines arranged for addition and subtraction, and has special reference to means for reciprocating the paper carriage so as to cause the printing to be done in two parallel columns.

The invention also has reference to means for controlling certain mechanisms of the computing machine, as, for example, the nonadd mechanism, the subtraction mechanism,

and the line-space mechanism, so that the first or left-hand column may contain identifying numbers-or other numbers which are not to be added, or so that the numbers printed in the rst column are added and those in the second column subtracted from the total of the first column, and so that the platen shall be turned to advance the paper only at the end of the line, that is to say, after the printing of a number in the second or right-hand column.

It is a special object of the invention to provide carriage-reciprocating mechanismand mechanism for controlling the mechanisms ofthe computing machine whichare of such nature that they may be readily used in conjunction with a machine of the character shown in my application Ser. No. 118,628, filed June 26, 1926, without necessitating reorganization of said machine.

In my application Serial No. 118,628, filed June 26, 1926, I have shown an adding and subtracting machine to which the present improvements are particularly, although not exclusively, adapted. The machine shown the general type disclosed in the Sundstrand Patents Nos.

1,198,487 and 1,583,102, and is provided with a cross-tabulating carriage arranged to control the mechanisms of the adding and subtracting machine so as to effect non-addition, subtraction and line-spacing, among other operations, atdesired times; The

means by whichthe carriage exercises such control comprises a stop plate attachedto the rear portion of the carriage and having'upon its lower side a number of rows of stop pins which in the leftward travel of the paper carriage engage slides which are compactly grouped together andlocated below the path of the stop plate, said slides in turn controlling various mechanisms adding and subtracting machine.

The machine shown in the present drawings is generally similar to the machine of said application Ser. No. 118,628, but it is provided with means for reciprocating the paper carriage between two positions, such a carriage. Referring now to the drawings, 1 is a paper carriage, 26 is the main rock shaft,

comprised the 950 carriage being known in-the art as a shuttle tion Serial No. 118,628.

being arranged to oscillate the shaft 26. 1010 is a plate detachably' secured to a iock shaft 1011 mounted on the paper carriage 1, the means for attaching'the plate 1010? to said rock shaft being like that fully disclosed in my said application Ser. No. 118,628, although it may be of any preferred character. 1012 is an operating lever, upon the righthand end of the shaft 1011 for turning said shaft to raise the rear edge of the plate 1010 The non-add mechanism, the means for set-- ting the computing mechanism to perform subtraction, and the means for controlling the line-space or paper-feed mechanism are controlled by slides 1045, 1069 and 1114, respectively. as fully explained in my said applica- The slides 1045, 1069 and 1114 are located side by side for reciprocation transversely of the machine. As in application Ser. No. 118,628, the. slides are located directly below and close tothe path of the plate 1010, although in this instance the plate 1010 does not carry any pins to operate the slides, but, on the contrary, forms part of the means for reciprocating the carriage 1.

Most of the elements of the carriage-reciprocating means and the devices whereby the carriage-reciprocating means and the slides 1045, 1069 and 1114 are controlled are contained within and supported upon a casing which constitutes a unit that may be readily applied to an adding, subtracting or duplex machine without necessitating the reorganization of the latter. The casing-referred to is indicated at 1200 in the drawings and is secured to the machine by means of a screw v 1201 (Fig. 1) extending through a lug 1202 on said casing and intothe base of the machine. The casing is further secured in place by means of two screws 1203 (Fig. 1) extending through openings in the carriage track bar 1108 and engaging tapped openings 1204 (Fig. 8) in a lug'or flange 1205' on the casing 1200.

The carriagereciprocating. means com- P prises a bar 1206 supported on the casing- 1200 for reciprocation transversely of the machine. At the left-hand end of the bar 1206 is a stud 1207 adapted to enter any one of three notches 1208 (Fig. 14) in the rear edge of the pivoted plate 1010 It will be seen that by depressing the lever 1012 the plate 1010 may be tilted out of engagement with the stud 1207, after which the carriage may be manually moved to place any one of the notches 1208 in engagementwlth the stud 1207', whereby a pair of columns may be printed at any one of three different. positions on the sheet.

The right-hand end of the bar 1206 is ad ustably connected by means of a screw 1209 (Fig. 6). and a slotted bracket 1210 to a connecting rod 1211 which in turn is ad ustably connected by means of a screw 1212 to a slotted crank arm 1214 fixed upon '2). The shaft 1215'is journaled for rotation in bearings 1216 and 1217 in the cas ing 1200.

The means comprises a rod 1218 mounted to slide back and forth in the casing 12 00. The forward end of the rod 1218 may be connected to the rock shaft 26 in any preferred manner, as, for example, by means of an angular member comprising an arm 1219 which is attached to the rod 1218, and an arm 1220 which is pivoted at 1221 to an arm 1222 fixed on the rock shaft 26. The arms 1219 and 1220 are connected by a web 1223 (Fig. 4) that slides in an elongated opening 1224 formed between-the base and the casing of the machine.

Rack teeth 1225 cut in the rod 1218 mesh with a pinion 1226 (Fig. 2) which is rotatthe, clutch collar- On the lower end of the clutch collar are diametrically opposite lugs 1232 each having .a vertical side adaptedto be engaged by the vertical wall 1227 of one of the notches in the hub of the'pinion 1226, and a rounded side adapted to'be engaged by the cam wall 1228. A coiled expansive spring 1233 normally holds the clutch collar 1229 in engagement with the hub of the pin- 1OI1.

In the forward stroke of the handle the pinion turns a little more than 180 counterclockwise, as viewed from above, the cam walls 1228 of the notches in the hub of said inion forcing the lugs 1232 up out of said notches, and the lugs dropping back into the. notches as the pinion completes'a half revolution. When the handle returns, the pinion is rotated in a clockwise direction, the walls 1227 of the notches in the pinion hub acting against the lugs 1232 and thus turning the clutch collar 1229 and the shaft 1215 through a half revolution, whereby the paper carriage 1 is moved from one to the other of its positions. To prevent the shaft 1215 from turning by momentum through more than 180 and thus to insure definiteness'in the stopping of the carriage in eachof its positlons, there is secured to the shaft-1215 a circular flange 1234 having two diametrically opposite notches 1235 corresponding in 7 slides 1045, 1069 .openings' '1265 in said plate.

periphery of theflange 1234. A coiled con I tractile spring 1239-pressesthe roller 1238 against the flange 1234.

Means may be provided for holding the clutch collar 1229 up out of engagement with the hub of the pinion 1226 when it is not desired to print in parallel columns. The means herein shown for this purpose comprises a lever 1240 (Fig. 1) pivoted at 1241 within the casing 1200, the forward end of said lever extending through an opening in the front wall ofthe casing1200 and being provided With a finger piece 1242. The rear end of the lever 1240 underlies a circular flange 1243 onsthe clutch collar. When the finger piece 1242 is depressed, thejrear end the lever 1240 lifts the clutch collar out of engagement with the hub of the pinion. In order yiel'dingly to hold the lever 1240 in either of its positions, I employ a latch 1244 pivoted at 1245 in the casing 1200 and havlng two notches adapted to receive a pin 1246,

on the lever 1240. A. coiled contractile spring 1247 presses the latch a ainst said pin.

The means for actuating, t e slides 1045, 1069 and 1114 comprises three slides 1248, 1249 and 1250 (Figs. 10 to 13 inclusive) alined with the first mentioned slides. These slides are mounted side by side and are supported upon two studs 1251 (Figs. 4 and 13) extending through slots. 1252 in the slides. The left-hand ends of the slides 1248, 1249 and 1250 are arranged to bear against the slides 1045, 1069 and .1114, respectively.

Coiled contractile springs 1253 tend to move the slides 1248, 1249 and 1250Jtoward the and 1114 respectively.

The means for moving the slide 1248 awa from the non-add slide 1045 against the tension of the spring 1253 comprises a plate 1254 (Fig. 9) which is virtually a bell-crank lever pivoted at 1255, said plate having thereon a roller stud 1256 adapted to be engaged by a cam surface 1257 on the slide bar1206 and also adaptedto run along the edge or dwell surface 1258 of said bar. A coiled contractile spring 1259 (Fig. 8) attached to apin 1260 on the plate 1254 holds the roller stud 1256 in engagement with the slide bar1206. A lug 1261 on the plate 1254 is arranged to engage a lug 1262 on the slide 1248 to push said side away from the non-add slide 1045.

The means for moving the slides 1249 and 1250 away from the subtraction slide 1069 and the line-space slide 1114, respectively, comprises a plate 1263 slidably mounted on screws 1264 extending through elongated On the lefthand end of the plate 1263 is a lug 1266'arranged to 'bear'against a pin 1267 on the plate 1254. On the opposite end of the plate 1263 is a fin er 1268 arranged to bear against lugs 1269 on the slides 1249 and'1250.

It will be seen that when the slide bar y receive a headed stud 1 mgs.

1206 moves toward the left from the position shown in Fig. 8 to that illustrated in Fig. 9 (thus positioning the carriage forprinting in the right-hand column) the cam surface,

Means is therefore provided for holding one or more of the slides 1248, 1249 and 1250 out of action. While this means maybe of any preferred character, I have herein shown three levers 1270 pivoted on the casing 1200 on an axis 1271 extending parallel with the I direction of movement of said slides. Each of these levers has a forwardly projecting finger piece 1272 and an upwardly extending arm which is guided in a slot 1273 Fig. 7), formed in' a stud 1274 projecting from the right-hand side of the casing 1200. On the upper end of each of the levers 1270 is a lug 1275 adapted to engage a lug 1276 on the slides 1248, 1249 and 1250, andthus hold said slides at the right-hand end of their stroke. i To hold the levers 1270 in adjusted position there is provided for each of said levers a {latch 1277 (Fig. 5) having two notches to 1278 on the lever. A coiled contractile spring 1279 holds the latch in engagement with said stud.

The nature of the work which may be done upon this machine is illustrated in Figs. 15, 16 and 17. Fig. 15 represents a specimen of work which may be done upon a machine having {two counters and equipped with the controls hereinbefore described. For full disclosure of one form of duplex machine to which the present invention may be applied,

reference may be made to my application Ser.

first counter may used to accumulate debits and the second counter for credits, the machine being normally set to accumulate in the first counter, but being operable by a slide such as the slide 1069 to withdraw the first counter from action and place the second counter in action.

During the production of the work represented in Fig. 15, the non-add slide 1248 would held outof action by raising the finger piece 1272 marked NA in The subtraction (or credit) finger piece and the paper feed finger piece would be desired.

the drawbe in their down position, thus leaving the slides 1249 and 1250 free to reciprocate.

Fig. 16 illustrates a specimen of work done upon an adding and subtracting machine similar to that disclosed in my application Ser. No. 070,665, the finger pieces 1272 being in the position just described.

Fig. 17 shows a specimen of work done with the subtraction slide 1249 held out of action, the non-add slide 1248 and the paper feed slide 1250 being free to reciprocate.

During the production of the work depicted in Figs. 15,16 and 17, the clutch lever 1240 is in its upposition, as shown in Figs. 1 and 4, thereby permitting the carriage to be reciprocated in the operation of the handle 27..

When it is desired to do single-column work, such as illustrated, for example, in my applications Ser. Nos. -67 0,665 and 720,187, the clutch lever 1240 is-moved into its down position, thus holding the clutch collar 1229 up out of engagement with the hub of the pinion 1226 andallowin the latter to oscillate idly.

It will be seen t at I have provided a selfcontained structural unit capable of application to an adding machine without modification of the latter and arranged to be readily connected to the operating handle and the paper carriage. It will also be evident that this unit is adapted to control certain mechanisms of themachine.

While the present embodiment of the in-- vention has been described in considerable detail, it will be understood that various modifications may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
